Exhibit 99.1

                 McDermott Reports Third Quarter 2005
    Results; Net Income of $58.5 Million, $0.80 Per Diluted Share

    NEW ORLEANS--(BUSINESS WIRE)--Nov. 8, 2005--McDermott
International, Inc. (NYSE:MDR) ("McDermott" or the "Company") today
reported net income of $58.5 million, or $0.80 per diluted share, for
the 2005 third quarter, compared to net income of $18.3 million, or
$0.27 per diluted share, for the corresponding period in 2004.
Weighted average common shares outstanding on a fully diluted basis
were approximately 73.3 million and 68.4 million for September 30,
2005 and September 30, 2004, respectively.
    Revenues in the third quarter of 2005 were $503.5 million,
compared to $450.2 million in the corresponding period in 2004,
reflecting increases at both consolidated segments. Operating income
was $74.1 million in the 2005 third quarter, compared to $39.8 million
in the 2004 third quarter. Operating income for the third quarter of
2005 included approximately $0.2 million of corporate qualified
pension expense, compared to $14.1 million of corporate qualified
pension expense in the third quarter of 2004. The reduction in
corporate qualified pension expense reflects the previously announced
spin-off of The Babcock & Wilcox Company ("B&W") pension plan and
related expense, which was completed on January 31, 2005. In addition,
beginning January 1, 2005, McDermott now allocates to its Government
Operations segment the pension expense related to that segment.
    "McDermott produced solid results from its two consolidated
businesses during the third quarter of 2005, and we continue to expect
that B&W will be reconsolidated in our results during early 2006,"
said Bruce W. Wilkinson, Chairman of the Board and Chief Executive
Officer of McDermott. "This was an active quarter for the Company,
including the activities associated with the currently proposed B&W
settlement and the signing of approximately $1.0 billion of new awards
at J. Ray."
    As a result of the August 29, 2005 announcement, and the
subsequent filing, of a currently proposed plan of reorganization for
B&W's Chapter 11 settlement, beginning in the third quarter of 2005,
McDermott has suspended recording the quarterly non-cash adjustment
associated with B&W's previously negotiated settlement, as the
previous plan is no longer considered probable. In the third quarter
of 2004, McDermott recorded an after-tax revaluation expense of $1.1
million associated with the revaluation expense of the previously
negotiated settlement.

    RESULTS OF OPERATIONS
    2005 Third Quarter Compared to 2004 Third Quarter

    Marine Construction Services Segment ("J. Ray")

    Revenues in the Marine Construction Services segment were $360.6
million in the 2005 third quarter, compared to $325.6 million for the
same period a year ago. The year-over-year increase in revenues
resulted primarily from increased project activity in worldwide
marine, the Middle East and Caspian regions, partially offset by
decreased fabrication activity on projects in Morgan City, Louisiana.
    Segment income for the 2005 third quarter was $63.7 million,
compared to $28.6 million in the 2004 third quarter. Major items
contributing to operating income in the 2005 third quarter were
international marine and fabrication projects. In addition, J. Ray
recorded a net benefit to operating income of approximately $36.4
million, primarily related to contract change orders and close-outs of
substantially completed projects. The 2004 third quarter included a
net benefit of $20.7 million, in aggregate, from favorable contract
cost adjustments on certain loss projects, gains on asset sales and
other items.
    At September 30, 2005, J. Ray's backlog was $1.7 billion, compared
to backlog of $1.2 billion and $1.4 billion at December 31, 2004 and
September 30, 2004, respectively. During the third quarter of 2005, J.
Ray signed contracts for new awards with projected revenue totaling
approximately $1.0 billion.

    Government Operations Segment ("BWXT")

    Revenues in the Government Operations segment increased $18.4
million, to $143.0 million, in the 2005 third quarter, compared to
$124.6 million for the same period a year ago. The increase was
primarily due to higher volumes in the manufacture of nuclear
components for certain U.S. government programs and increased revenues
from commercial nuclear environmental services, as well as other
commercial work, including increased uranium downblending activity.
    Segment income decreased $9.5 million, to $19.3 million, compared
to the 2004 third quarter, primarily due to the corporate allocation
to BWXT of $5.3 million related to qualified pension expense in the
third quarter of 2005, which in 2004 and prior periods was recorded in
the corporate segment. In addition, increased expenses related to
facility oversight and stock-based compensation were recorded in the
2005 third quarter, partially offset by higher volumes in the
manufacture of nuclear components and from commercial nuclear
environmental services.
    At September 30, 2005, BWXT's backlog was $1.5 billion, compared
to backlog of $1.7 billion and $1.5 billion at December 31, 2004 and
September 30, 2004, respectively.

    Corporate

    Unallocated corporate expenses were $9.3 million in the 2005 third
quarter, a decrease of $8.3 million compared to the 2004 third
quarter. The decrease was primarily due to a reduction in qualified
corporate pension expense during the third quarter of 2005 as a result
of the BWXT pension allocation and the spin-off of B&W's pension
assets and liabilities into a new B&W-sponsored pension plan.

    Other Income and Expense

    The Company's other expense for the third quarter of 2005 was $5.4
million, compared to $9.1 million in the third quarter of 2004, which
included net interest expense of $3.8 million and $7.6 million in the
respective quarters.
    As mentioned above, during the 2005 third quarter, McDermott
suspended the revaluation of certain components related to the
previous settlement cost of the B&W Chapter 11 proceedings. McDermott
expects that the currently proposed settlement will be recorded in
McDermott's financial statements on the effective date of the
currently proposed plan of reorganization. See McDermott's Form 10-Q
for the period ending September 30, 2005 for additional information
regarding the accounting for the currently proposed B&W settlement.

    THE BABCOCK & WILCOX COMPANY

    McDermott wrote off its remaining investment in B&W of $224.7
million during the second quarter of 2002 and has not consolidated B&W
with the Company's financial results since B&W's Chapter 11 bankruptcy
filing in February 2000. In accordance with the currently proposed
settlement related to B&W's Chapter 11 proceedings, the Company
currently expects that B&W will be reconsolidated in early 2006.
    During the third quarter of 2005 on a deconsolidated basis, B&W's
revenues were $373.1 million, an increase of $94.1 million compared to
the third quarter of 2004. In the 2005 third quarter, B&W recorded an
estimated net expense of $468.4 million related to the currently
proposed Chapter 11 settlement announced on August 29, 2005. As a
result of this expense, B&W's operating loss for the third quarter of
2005, prepared in accordance with generally accepted accounting
principals ("GAAP"), was $441.6 million. Excluding the net expense
related to the Chapter 11 settlement from B&W's GAAP operating income,
B&W's non-GAAP operating income for the third quarter of 2005 was
$26.7 million(1). During the third quarter of 2005, B&W recorded
approximately $6.8 million of pension expense, which in prior years
resided in the corporate segment. In the third quarter of 2004, B&W's
operating income was $20.6 million.
    At September 30, 2005, B&W's backlog was $1.6 billion, compared to
backlog of $1.5 billion and $1.3 billion at December 31, 2004 and
September 30, 2004, respectively.
    (1) Reconciliation of B&W non-GAAP operating income: GAAP
Operating Loss of $441.6 million, plus the currently proposed B&W
Chapter 11 settlement expense of $468.4 million, for a result of $26.7
million.

    OTHER INFORMATION

    About the Company

    McDermott International, Inc. is a leading worldwide energy
services company. The Company's subsidiaries provide engineering,
fabrication, installation, procurement, research, manufacturing,
environmental systems, project management and facility management
services to a variety of customers in the energy and power industries,
including the U.S. Department of Energy.
    In accordance with the Safe Harbor provisions of the Private
Securities Litigation Reform Act of 1995, McDermott cautions that
statements in this press release, which are forward-looking and
provide other than historical information, involve risks and
uncertainties that may impact the Company's actual results of
operations. These forward-looking statements include statements
relating to backlog, the proposed settlement of the B&W Chapter 11
proceedings and the accounting treatment expected to be applied to
that settlement. Although we believe that the expectations reflected
in those forward-looking statements are reasonable, we can give no
assurance that those expectations will prove to have been correct.
Those statements are made by using various underlying assumptions and
are subject to numerous uncertainties and risks, including, but not
limited to, risks that revenues in backlog may not be realized in the
amounts described as a result of changes in the contracts and other
various factors, and the B&W Chapter 11 settlement may not be
finalized on the terms we expect or within the time frame we
anticipate. If one or more of these risks materialize, or if
underlying assumptions prove incorrect, actual results may vary
materially from those expected. For a more complete discussion of
these and other risk factors, please see McDermott's annual report for
the year ended December 31, 2004 and its 2005 quarterly reports filed
with the Securities and Exchange Commission.
    McDermott has included in this press release B&W's operating
income/(loss) for the three-months ended September 30, 2005 on both a
GAAP and a non-GAAP basis. The non-GAAP measure excludes an expense
related to B&W's currently proposed Chapter 11 proceedings settlement
which management considers to be outside B&W's customary business.
McDermott believes this non-GAAP measure provides meaningful insight
into B&W's operational performance and will use this measure to
evaluate B&W's operations for budget planning and performance goals. A
reconciliation of the difference between these measures is presented
in the footnote within the B&W section above.
